⚙️ Simple Machines Workshop: Levers, Pulleys, Gears & Contraptions

A cosy workshop with seven working simple machines: lever, ramp, pulley, gears, wheel and axle, screw jack and wedge. Drag the handles, read live force, distance, work and efficiency meters, solve six challenges and ring the bell with a chain of machines. Real equations, friction and an energy check.
